But the request itself is not wrong, i.e. no reason to return HTTP 400. It'll be hard to tell if the YAML or the request is invalid.

@lholecek and I discussed that over IRC. As discussed internally: if we'll ever bump the api version we're going to change this status code in the new version.

@gnaponie in my opinion you don't need to bump the API version to change the status code if it was set as a mistake. I think it can be treated as a bug and called out in the release notes.

@mprahl this might be an idea. @lucarval are you ok if we do that?

That change would break rpkg which already checks HTTP 400 to indicate errors in gating.yaml.

Good point, @lholecek. In case we change the status code we should include this rpkg change in the things to do.
